DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a rear binding for alpine skis.

To alpine ski, a skier's shoe is held in place between a front binding (i.e., doe piece) that holds the front edge of the shoe and a rear binding (i.e., heel piece) that holds the shoe's rear edge. Keep it fixed. These two bindings are designed to come off and release the shoe if the skier falls. Each of these fasteners has a main body integral with a jaw that holds the end of the shoe and a base that carries a mechanism for energizing the jaw, which allows for flexible clamping of the shoe, and a rear section. The body of this rear binding is generally slidably mounted via its base on a sliding plate fixed on the ski, so that the binding can follow the deflection movements of the ski. The body can be moved slightly backwards on this sliding plate against the action of the elastic return device. This return device is

BRIEF DESCRIPTION OF THE DRAWINGS In the following, various embodiments of the invention will be explained by way of example and without being limited to these embodiments, with reference to the accompanying drawings.

The rear binding, or heel piece, shown in Figures 1 to 3 and designated in its entirety by the number 1, is attached to the ski 2.
Mounted in a longitudinally adjustable position on the top.

This heel piece 1 has a main body 3, which has a jaw for holding the rear end of the shoe at its front part, and whose lower part is interlocked with a base 4. The base 4 is mounted so as to slide longitudinally on a sliding plate 5 fixed on the upper horizontal surface of the ski 2 by any suitable means, for example screws. The sliding plate 5 is attached to the base plate 4 of the body 3 of the fastener, as shown in FIGS. 1 to 3.
Is it made up of metal plates that are combined from the beginning with
or.

Configured on the basis of some other variant, the sliding plate 5 constitutes a platform fixed on the upper longitudinal ridge 2a of the ski 2, which ridge is wider than the width of the ski 2. It also has a rectangular cross section of narrow width. The width of this platform, which becomes the sliding plate 5a, is wider than the width of the protrusion 2a but narrower than the width of the ski 2. As a result, both longitudinal ends of this platform are in the longitudinal direction of the protrusion 2a. The cross section of the pedestal 4 of the main body 3 extends slightly protruding from both ends of the ski but does not reach the longitudinal sides 2b and 2C of the ski 2. The upper horizontal core part 4a extends downwardly along both ends thereof in the longitudinal direction with two side parts 4b and 4c bent in the shape of hooks facing each other and opening inward. have. The width of the open part on the lower side of the pedestal 4, which has a C-shaped cross section, is made slightly wider than the width of the narrowed part 5a of the sliding plate 5 (FIG. 3), so that the sliding plate 5 initially The heel piece 1 can be inserted into the sliding plate 5 by a movement perpendicular to the plane of and then by a longitudinal movement on this sliding plate. In any case, the pedestal 4 and the sliding plate 5 are arranged so that the pedestal 4 can be slid in the longitudinal direction.
The main body 3 is shaped to be able to slide longitudinally on the sliding plate 5 fixed to the ski, while also being able to engage with each other with a minimum lateral clearance.

so that the shoe can be gripped between the front binding and the heel piece (not shown in the figure), and so that this heel piece 1 can follow the deflection movement of the ski.
This heel piece 1 is mounted on a slide guide plate 5 so that it can slide rearwardly against the force of the elastic return device 6. According to the invention, this elastic return device w6 is provided inside the ski 2, in particular in the longitudinal projection 2a of the ski, as well as in the slide guide plate 5.
It is installed in a housing provided within the housing. This housing has a longitudinally long hollowed out part 7 provided in the upper surface of the longitudinal protrusion 2a of the ski 2, and a hollowed out part provided in the slide guide plate 5 and formed in the upper part of the hollowed out part 7. The elastic return device 6 of the body 3 is made up of a longitudinally long 68 extending with the same length as the body 3.
In this non-limiting embodiment, it is constituted by a separate return cartridge that fits snugly into a housing constituted by the overlap of cutouts 7 and 68. This return cartridge 6 has the shape of a parallelepiped whose dimensions exactly match the dimensions of the space fixed by the overlap of the hollowed out portions 7 and 68. However, this longitudinal parallelepiped shape is not limiting, and any other suitable shape suitable for the return device may be considered.

This return cartridge 6 is made up of two parts: an upper box 9 and a lower cover 11 fixed to this box 9 by screws 12. Upper box 9
and the lower cover 11.

A true elastic return device is housed in the body 3. In particular, a device 13 which constitutes a coupling or stress transmission device between the base plate 4 and the ski 2 and at the same time constitutes a locking device for length adjustment, and a return spring which applies a forward elastic stress to this locking device 13. 14, this locking device 13 is constituted by an upper horizontal plate 13a provided with a connecting member consisting of teeth 15 projecting upward. This tooth 15 passes through a longitudinally long groove 16 provided in the upper bottom plate 9a of the box 9. A relatively large gap is provided between the ends of the groove 16 and the teeth 15, so that the locking device 13 can be moved longitudinally with limited amplitude, i.e.
The heel piece 1 can be moved to move backward. The upper horizontal plate 13a of the locking device 13 is extended at its rear end by a right-angled edge 13b forming a rear front wall extending downwardly and supporting the front end of the return spring 14. This spring is a compression spring whose rear end is pressed against the rear side wall 9b of the box 9. The front end of the upper horizontal plate 13a is pressed against a slope 9c that slopes from bottom to top and from rear to front. This inclined surface 9c becomes the inner surface of the front wall 9d of the box 9.

The base plate 4 also has, at the front of its upper horizontal core 4a, a series of notches 17 arranged longitudinally to form a rack.

These notches 17 are formed by through holes drilled in the core portion 4a of the base plate 4, and these notches allow the heel piece 1 to take various longitudinal positions on the slide guide plate 5. It's decided. These cutouts 17 may be of any suitable shape, in particular of the shape of a transversely elongated rectangle in plan view, as shown in FIG. There may be.

, in the locked position, the locking device 13 locks the box 9 under the action of the return spring 14, as shown in FIG.
in the upper horizontal position inside. This is because this spring pushes the plate 13a forward and the front end of this plate slides on the inclined surface 9c, pushing the entire locking device 13 up into its upper horizontal position. In this position, the teeth 15 are
It extends through the groove 16 in the bottom plate of the box 9 and has a notch 17.
Therefore, the height of the tooth 15 is smaller than the bottom plate 9a of the box 9.
and the thickness of the core portion 4a of the base plate 4. In this locked position,
The heel piece 1 can be pushed elastically backwards and can grip the shoe and also allows the shoe to move during sliding. When the heel piece 1 is stressed backwards, its base plate 4 drives the teeth 15 as well as the entire locking device 13 in the same direction against the force of the return spring 14.

If it is desired to change the adjustment of the longitudinal position of the heel piece 1 on the slide guide plate 5, it is only necessary to store the locking device 13 inside the box 9, as shown in FIG. For example, a tool 18 such as a screwdriver
This can be done by inserting it at right angles through the notch 17 in which the tooth 15 is located and pushing this tooth 15 downwards into the box 9 so that it comes out of the notch 17. To facilitate this retracting movement, the tooth 15 has a recess 15a on its upper surface, i.e. the tool 18.
It is convenient to have a recess for inserting the end. If the tooth 15 is pushed downward and stored in the box 9 under the core 4a of the base plate 4, the slide guide plate 5
On the top, the body 3 of the heel piece can be slid in either direction along the longitudinal direction.

Box 9 closed by cover 11, return spring 14
The return cartridge 6 with the locking device 13 can be delivered together with the ski 2 or the heel piece 1.

For example, different color-coded variations in the stiffness of the spring 14 and/or the amplitude of the return stroke and/or the position of the teeth 15 on the locking device 13 (thereby varying the length adjustment for the body 3 of the fixture) can be used. Different types of return cartridges 6 can optionally be used. When installing the heel piece 1 on the ski 2, the operator first places the return cartridge 6 in the housing 7.8 which is previously provided in the ski 2 and the slide guide plate 5. , Next, the operator inserts the body 3 of the heel piece into the slide guide plate 5.The operator first moves the body 3 of the heel piece to the final target position in the longitudinal direction, which varies depending on the position of the doe piece and the length of the shoe. let It should be noted here that during this movement the tooth 15 has to pass through 9, in most cases one or more notches 17, before reaching the final destination notch. In this case, in order to eliminate the need to force the tooth 15 downward each time it passes through each notch 17, for example using a screwdriver 18 as shown in FIG.
The base plate 4 of the heel piece can also be equipped with a removable bottle that closes the cutout 17. In this way, before installation, it is sufficient to simply remove the bottle corresponding to the correct position in the longitudinal direction of the heel piece 1.

Also at the rear of the teeth 15 of the locking device 13.

A chamfered portion 15b as shown in FIG. 4 may also be provided. This chamfered portion 15b is inclined from bottom to top and from rear to front, so that the forward thrust applied to the body 3 and base plate 4 as indicated by the arrow f in FIG. , the teeth 15 and the locking device 13 are pushed downward by the force applied to the chamfer 15b through the rear end of each notch 17. In order for this to occur, the chamfer 15b extends slightly below the rear end of one notch 17 in the locking position, that is, when the teeth 15 are maximally engaged with this notch 17; This rear end is the chamfered portion 15b.
It is clear that it must be possible to slide over the top. Meanwhile, during use, the base plate 4 has teeth 15.
and when applying a rearward stress to the locking device 13, the tooth 15 remains fixed in the notch 17 with which it meshes. For the body 3 of heel piece 1
It is necessary to insert it into the slide guide plate 5 from the rear to the front.

The heel piece 1 shown in FIG. 3 is combined with a removable ski brake 19, which can be attached to the heel piece 1 by screws 21. A cutout 17 provided in the upper horizontal core 4a of the base plate 4 is located below the base plate 19a of the ski brake 19 when the ski brake 19 is fixed to the heel piece 1. Therefore, in order to access the teeth 15 of the locking device 13, it is necessary to remove this ski brake 19 beforehand. However, if a pin to hide the notch 17 or a tooth 15 with one chamfer 15b is used, the locking device 13
It is therefore no longer necessary to have direct access to the heel piece 1, so that the heel piece body 3 can be mounted on the sliding guide plate 5 together with the ski brake 19 in combination with the heel piece 1. On the other hand, when changing the longitudinal position of the heel piece 1, the return cartridge 6
It may be necessary to remove the ski brake 19 in order to gain access to the teeth 15 of the locking device 13 in order to store the locking device 13 in the box 9.

In the variant embodiment shown in FIGS. 5 to 7, the housing 7.8 of the return cartridge 6 is longer than the return cartridge 6 and the housing 7.8.
A removable spacer 22 is used to fill the space between one of the 8 front walls. This removable spacer 22 may be installed at the rear end of the housing 7.8, as shown in FIGS. 5 and 6, or at the rear end of the housing 7.8, as shown in FIG. The two positions, which may be located at the front end, correspond to different longitudinal positions of the teeth 15 of the locking device 13 and thus one for example in the range of adult shoes and in the range of children's shoes. This corresponds to two different length adjustment ranges.

Instead of this one removable spacer 22,
Several sets of spacers of different thickness may be used as shown in FIGS. 8 and 8A, in which case the return cartridge 6 is shorter than the housing 7.8 by a length Different thicknesses a, b, c,
Four spacers 22a, 22b, 22c, 2 with d
2d is retained within this housing. However, the sum of these thicknesses shall be equal to the difference in length X between the return cartridge 6 and its housing 7.8. These spacers thus provide teeth 15, i.e. of the heel piece 1, at the rear and/or front part of the return cartridge 6, between the front wall of the return cartridge 6 and the front wall of the housing 7.8. They can be installed in a certain order based on the longitudinal position to be taken.

FIG. 8 shows a case where these four spacers 24a to 24d are arranged next to each other at the rear of the return cartridge 6, and FIG. 8A shows a case where the thinnest spacer 24d is arranged at the front of the return cartridge 6. However, the remaining three spacers 24a, 24b, and 24c are arranged at the rear of this cartridge.

In the variant embodiment shown in FIG. 8, the ski 2 and the sliding guide plate 5 have two housings 7.8 arranged next to each other and longitudinally offset from each other. The return cartridge 6 can be installed in either of these housings 7.8, making it possible to provide the teeth 15 of the locking device 13 with two different longitudinal positions. The base plate 4 is provided with two series of notches 17 arranged in the longitudinal direction to match the two housings 7.8 mentioned above, respectively, in the core part 4a.

FIG. 10 shows a return cartridge 6 that can be reversed, i.e. installed in either direction.
It is shown. In this case, the return cartridge 6
Box 9 has two opposing compression springs 14 and 1
4a is housed, and a locking device 13 is installed between these springs. The spring 14 is connected to the left side wall 9b of the box 9 and the locking device i! 13 and a right-angled edge 13b that forms the left side wall of the frame 13. Another compression spring 14a is installed between the right side wall 9d of the box 9 and a free piston 23 mounted to slide longitudinally inside the box 9. This piston 23 is a locking device! The mouthpiece device 13 has a left front surface 23a that is sloped to form a sloped surface that supports the right end of the horizontal plate 13a of 13. Always press upwards. In the equilibrium state, the teeth 15 are moved at different distances 1 from both longitudinal ends of the return cartridge 6 due to the elastic force.
They are held at positions 1 and 12 apart. As a result, by changing the installation direction of the return cartridge 6, the springs 14 and 1 can be fixed regardless of the position of the cartridge 6.
Two different longitudinal positions can be provided for the teeth 15 of the locking device 13, which are always stressed in the forward direction by elastic forces by either of the teeth 4a.

In the variant embodiment shown in FIG. 11, the teeth 15 of the locking device 13 are connected to a cursor 24 mounted longitudinally adjustable in a downwardly open housing 25 provided in the base plate 4 of the heel piece 1. It engages with a notch 24a provided in the lower surface. The longitudinal position of this cursor 24 is determined by a screw 2 extending in the longitudinal direction and having a head 27 mounted on a horizontal wall provided at the rear of the base plate 4 such that it cannot move in the axial direction but can rotate.
It can be adjusted by 6. The externally threaded shaft of this screw 26 is screwed into a longitudinally threaded hole of the cursor 24 .

Therefore, the cursor is fixed by inserting the teeth 15 of the locking device 13 into the lower notch 24a of the cursor 24, but by turning the screw 26 in either direction, The position of can be changed slightly.

In the modified embodiment shown in FIG. 12, the return cartridge 6 includes an adjusting screw 2 for adjusting the longitudinal position of the heel piece.
There are 8. This screw 28 extends longitudinally inside the return cartridge 6 and has an externally threaded front part 29 by means of which it forms a rear lateral wall of the locking device 13. right-angled edge 13b
It is screwed inside. This screw 28 has, at the rear of its externally threaded front part, a return spring 1 which has its rear end resting on an intermediate vertical lateral wall 32 of the box 9 of the cartridge.
It has a collar 31 that supports the front end of 4. The shaft portion of the screw 28 passes through this intermediate wall, and the head 33 of this screw is connected to the intermediate vertical wall 32 of the box 9 and the rear horizontal wall 9.
It is located within a space 34 delimited by b. An opening 35 is provided in the upper bottom plate 9a of the box 9 above the space 34, so that a tool for turning the screw 28 can be inserted into this space. For this reason, it is better to have teeth on the head 33 of this screw. In this way, by applying force to the head 33 with teeth and rotating the screw 28, the locking device 13 and the locking device 13 can be interlocked with each other. The longitudinal position of the teeth 15 can be varied. This tooth 15 is inserted into a hole 36 drilled in a retractable tongue 37 associated with the body. When the heel piece 1 moves backward, that is, the 12th
When moving to the left in the figure, the body of the heel piece 1 moves the locking device 13 via the tongue 37,
The return spring 14 is further compressed. This movement is made possible by the fact that the head 33 of the screw 28 is free to move backwards within the rear space 34. To separate the body of the fastener 1 and the locking device 13, lift the retractable tongue 37 and
Hole 3 provided in this tongue 37 for inserting teeth
This can be done very easily by removing the teeth 15 of the locking device 13 from 6.

FIG. 13 shows that the return spring 14 and the locking device i13 of the elastic return device can be mounted on the housing 7.8 of the ski 2 and the slide guide plate 5 without using the external box 9 as in the previously described examples. 2 shows a variant embodiment, which is housed directly within. In this case, the return spring 14
The rear end of the housing 7.8 is supported directly on the rear side wall of the housing 7.8. Further, the front end of the horizontal plate 13a of the locking device 13 having the fixing teeth 15 projecting upward is connected to the housing 7.
A spacer 38 is installed in the frontmost part of the housing 8 so as to touch the front side wall of the housing.The spacer 38 is pressed against the inner surface 38a forming an inclined plate that is inclined from the bottom to the top and from the rear to the front. is set up. The inner inclined surface 38a of this spacer 38 is connected at its upper end to a projection 38b of the spacer 38 which extends rearward and forms an upper position stop for the front end of the horizontal plate 13a of the locking device 13.

In the variant embodiment shown in FIGS. 14 and 15, the coupling device of the elastic return device 6 constituted by the return cartridge includes a stress transmission device 13, which is connected to its upper horizontal plate. 13a has a plurality of holes 41 spaced longitudinally from each other, into which coupling members constituted by removable pins 42 can be inserted. This pin 42 extends vertically through a longitudinal groove 16 provided in the upper base plate 9a of the box 9 and through one of the notches 17 in the core 4a of the base plate 4. Therefore, by arbitrarily selecting the notch 17 of the base plate 4 into which the pin 42 is inserted and the hole 41 of the stress transmitting device 13, it is possible to adjust the longitudinal position of the base plate 4 and the heel piece body 3 in the rest state. It is. The pin 42 is inserted from top to bottom through the notch 17, groove 16 and hole 41. In order to limit this insertion movement, a horizontal projection 42a is provided at the upper end of the pin 42, and this projection 42a hits the upper surface of the core portion 4a of the base plate 4 when the insertion is completed. It also serves to insert a tool such as a screwdriver between this protrusion and the top surface of the core 4a of the base plate 4 and pull out the pin 42 when you want to adjust the longitudinal position of the heel piece 1. The important thing to note here is that
In this embodiment, the front end of the upper horizontal plate 13a of the stress transmitting device 13 also has a right-angled edge 13c extending downward, and this right-angled edge forms a front side wall supported by the lower cover 11. That's what it means. As a result, when the body 3 of the fastener moves in the longitudinal direction, the stress transmitting device 1
3 is guided inside the return cartridge 6 and slides horizontally.

In the variant embodiment shown in FIGS. 16 and 17, on the upper surface of the upper horizontal plate 13a of the stress transmitting device 13 there is an upwardly extending sleeve or duct 13d having approximately the same height as the height of the groove 16; The upper end of the duct 13d is.

It is located at approximately the same height as the top surface of the bottom plate 9a of the box 9.

Therefore, the duct 13d is connected to the removable pin 42.
It forms a blind hole for inserting it all the way.
